Definitions

  • Rings so-called multi-crimp rings, are manufactured in different designs.
  • a tube welded axially or along a helix is divided into rings of the desired width, which are then deburred. Disadvantages of this process are the high minimum production quantities required for cost reasons, the correspondingly low flexibility with different diameters and the high storage costs of the blank pipes.
  • lengths corresponding to the ring circumference are cut straight or obliquely from a band which has been split and deburred according to the desired ring width, and the ends of which are welded; please refer US 2010/0187767 A1 , which is considered the closest prior art.
  • EP 1 752 247 A1 it is known, when butt welding a workpiece subjected to bending, to carry out the weld seam in two partial seams which overlap one another at the outer ends in the central region in order to avoid notches on the outer edge of the workpiece.
  • the invention is based on the general object of at least partially eliminating disadvantages such as occur in comparable methods for producing a welded ring.
  • a more specific object of the invention can be seen in providing a method with which welded rings can be produced with a weld seam that is as uniform as possible.
  • This object is achieved in that an offset in the circumferential direction of the ring is provided on the band ends to be welded to one another in the plane of the band and the welding is carried out from both sides of the ring from the outside inwards up to the offset. It takes place A flush weld takes place on both ring edges.
  • the offset has the effect that the effect of the melt flowing away when the two weld seams overlap is reduced in the middle of the strip, thereby achieving a better weld quality in the overlap area.
  • Fig. 1a the joint at which the two band ends 10, 11 are welded to one another has an offset in the form of a step 12 lying in the plane of the band, at which a part 13 projecting at one band end 10 faces a recessed part 14 at the other band end 11.
  • the step 12 is formed in the middle between the two band edges 15, 16.
  • the design after 2a and 2b differs from that after 1a and 1b in that the offset is formed as an indentation 23 lying in the band plane at one band end 10, into which a complementary bulge 24 engages at the other band end 11.

Description

    Stand der Technik
  • Ringe, sogenannte Multi-Crimp-Ringe, werden in unterschiedlichen Ausführungen hergestellt. In einem bekannten Verfahren wird ein axial oder längs einer Schraubenlinie geschweißtes Rohr in Ringe gewünschter Breite zerteilt, die anschließend entgratet werden. Nachteilig bei diesem Verfahren sind die aus Kostengründen benötigten hohen Mindestproduktionsmengen, die dementsprechend geringe Flexibilität bei unterschiedlichen Durchmessern und die hohen Lagerhaltungskosten der Rohlings-Rohre.
  • Bei einem alternativen Herstellverfahren werden von einem entsprechend der gewünschten Ringbreite gespaltenen und entgrateten Band dem Ringumfang entsprechende Längen gerade oder schräg abgeschnitten und gebogen, deren Enden verschweißt werden; siehe US 2010/0187767 A1 , die als nächstliegender Stand der Technik angesehen wird.
  • Beim Verschweißen der Bandenden lässt sich beim Einfahren des Schweißvorgangs eine mit der Ringkante im Wesentlichen bündige Schweißung erzielen. Demgegenüber entsteht beim Schweißaustritt an der anderen Ringkante eine mit der Kante unbündige Geometrie.
  • Aus EP 1 752 247 A1 ist es bekannt, beim Stumpfschweißen eines auf Biegung beanspruchten Werkstücks die Schweißnaht in zwei Teilnähten auszuführen, die an den äußeren Enden beginnend im mittleren Bereich einander überlappen, um Kerben am Außenrand des Werkstücks zu vermeiden.
    • Abriss der Erfindung
  • Der Erfindung liegt die generelle Aufgabe zugrunde, Nachteile, wie sie bei vergleichbaren Verfahren zum Herstellen eines geschweißten Rings auftreten, mindestens teilweise zu beseitigen. Eine speziellere Aufgabe der Erfindung kann darin gesehen werden, ein Verfahren anzugeben, mit dem sich geschweißte Ringe mit möglichst gleichmäßiger Schweißnaht herstellen lassen.
  • Die Lösung dieser Aufgabe gelingt dadurch, dass an den miteinander zu verschweißenden Bandenden ein in der Bandebene liegender Versatz in Umfangsrichtung des Rings vorgesehen ist und die Schweißung von beiden Ringseitenkanten her von außen nach innen bis zu dem Versatz erfolgt. Dabei findet an beiden Ringkanten eine bündige Schweißung statt. Der Versatz bewirkt, dass in der Bandmitte der Effekt des Wegfließens der Schmelze bei einer Überlappung der beiden Schweißnähte reduziert und dadurch eine bessere Schweißgüte im Überlappungsbereich erzielt wird.
    • Kurzbeschreibung der Zeichnungen
  • Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnungen näher erläutert. Darin zeigen:
    • Fig. 1a und 1b perspektivische Darstellungen eines Teils der Stoßstelle eines zu einem Ring gebogenen Bandes vor und nach dem Verschweißen und
    • Fig. 2a und 2b ähnliche Darstellungen mit alternativer Gestaltung der Stoßstelle.
    Ausführungsbeispiele
  • In Fig. 1a weist die Stoßstelle, an der die beiden Bandenden 10, 11 miteinander verschweißt werden, einen Versatz in Form einer in der Bandebene liegenden Stufe 12 auf, an der ein am einen Bandende 10 vorspringender Teil 13 einem zurückspringenden Teil 14 am anderen Bandende 11 gegenübersteht. Die Stufe 12 ist in der Mitte zwischen den beiden Bandkanten 15, 16 ausgebildet.
  • Beim Schweißvorgang wird von beiden Bandkanten 15, 16 ausgehend bis zu der Stufe 12 geschweißt. Durch den Versatz wird eine bessere Schweißgüte im Bereich der Überlappung der beiden Schweißnähte 17, 18 an der jeweiligen Stelle erzielt. Der Versatz ist nur so stark, dass auch an dieser Stelle eine kontrollierte Schweißverbindung der aneinender stoßenden Bandenden 10, 11 entsteht.
  • Besteht keine Unterbrechung (Versatz) an der Überlappungsstelle der beiden Schweißnähte 17, 18, so entsteht an den aneinander stoßenden Bandenden zweimal ein Schmelzbad. Dies führt im Überlappungsbereich zu verringerter Schweißgüte. Durch den Versatz fallen die Auswirkungen des zweifachen Schmelzbades auf die Schweißgüte geringer, konsistenter aus.
  • Die Gestaltung nach Fig. 2a und 2b unterscheidet sich von der nach Fig. 1a und 1b dadurch, dass der Versatz als in der Bandebene liegende Einbuchtung 23 am einen Bandende 10 ausgebildet ist, in die eine komplementäre Ausbuchtung 24 am anderen Bandende 11 eingreift.
